I bought a 95 civic w b18b, motor is in good shape, doesnt use oil or anything. My goal is for it to pass smog, since im new to cali. Right now the o2 sensor isnt even hooked up, but its there. Its running a chipped ecu right now, which is why im assuming it can run with no o2 sensor. What do i need to do? Get a usdm ecu, and convert to from 0bd2 to obd1? I should mention my LS is a 97. Im not gonna be able to ride around with WI plates forever, someone please give me some advice.
